Abstract
ERS-tandem mode, multi source data, coherence map, neural network, land use classification
Microwave data (ERS-1 and ERS-2) and optical data (SPOT-XS) were used for the classification of an area with different
land use classes. Classifications were executed for the optical data alone and for a combination of the three data sets. Two
classifiers, one based on the maximum likelihood algorithm and the other on a neural network approach, were applied. From
the ERS tandem mode SAR data a coherence map was created and included in the classifications in the form of an
additional dimension in the feature space. The accuracy and reliability of the four classifications are presented and the
results discussed.
1. INTRODUCTION
Optical and microwave data can provide complementary
information about objects that cover the Earth surface.
Optical data contains the information about the reflection of
the solar energy in selected parts (bands) of the spectrum.
The image elements (pixels) of optical sensors can be seen
as vectors of which the components represent the
reflection in the different bands. Image elements of
microwave data consist of two components, the magnitude
and the phase which are stored as complex numbers in two
"layers". If optical and microwave data sets are correctly
combined, the resulting product will convey more
information and could prove to be more useful then either
image alone.
The information contained in the multi-sensor data can be
extracted visually or by computer supported methods. In
computer analysis, a suitable classifier is needed to handle
the optical and microwave sensor data. Since the nature of
the two data sources is different, which results in different
frequency distributions of the data, it makes sense to use
the neural network approach to analyze this data. Neural
network classifiers are able to handle the multi-nature data
from different sources.
Phase information of microwave image data is mainly used
in the field of interferometry. Interferometric processing of
SAR data from space combines images from two passes of
a sensor system or combines the data from two sensor
systems in tandem mode. This process derives precise
measurements of the differences in path length to the two
sensor positions. The main output of interferometry of SAR
data is topographic information related to terrain heights or
the monitoring of positional changes of the Earth surface. A
strong relation exists between the quality of these products
and the correlation of the complex data sets. In those areas
where high correlations exist an accurate Digital Terrain
Model can be realized. On the other hand, height
information cannot be extracted in areas with low
correlation. So the quality of the products is characterized
by the "interferometric correlation”, which is a measure of
the variance of the interferometric phase estimate. The
amount of correlation is a function of the system noise, the
volume scattering, baseline configuration and temporal
change. Consequently, the interferometric (de)correlation
itself contains significant thematic information that can be
useful for several other applications.
In SAR images, the magnitude and the phase of each
element are the coherent summations of the back scattering
and phase of the individual scatterers inside a resolution
cell. The variation in the overall phase and the overall
magnitude of cells with equal cover type will appear as
speckle. However two images taken from the same position
at the same moment will be identical (neglecting system
noise). If two images are taken from different positions
and/or instants of time, variations in pixels representing the
same surface cell will appear.
If the structure or chemical composition of the ground-cover
changes, then the amount of temporal decorrelation will
vary. This variation can contain information about the type
of ground-cover and/or the situation in which it exists.
Influence on temporal changes, in case of space borne
sensor-systems, can be minimized by a high temporal
resolution of the system or by a combination of two
"identical" systems in a tandem mode. The ERS-1 and
ERS-2 systems satisfy this last requirement.
Correlation between the data from a cell is expressed in
terms of the summated phase and intensity of the resulting
back scatter. A cell is considered to contain a set of
individual back scatterers distributed over the cell. The
amount of energy back scattered by the individual
scatterers can be equal or can vary and the positional
